Roman wall-painting in southern Gaul (Gallia Narbonensis and Gallia Aquitania)

In the Greek world, the practice of decorating walls with painted stucco emerged in the 5th or 4th c. B.C. and was at first limited to public and religious monuments and the palaces of rulers, later spreading to the houses of the aristocracy. In the homes of the nobility, painted decoration enhanced the ornamentation of rooms used for receiving visitors, such as the dining room (andron), in which the floors were sometimes decorated with mosaics, most often with geometric motifs. In the wealthiest abodes, as seen at Pella in the 4th c. B.C., Alexandria, or on Delos in the 2nd c. B.C., a mosaic picture called anemblemasometimes lay at the centre of the mosaic. In the realm of domestic art, in the Hellenistic age images were restricted to the mosaic floors. The walls were ornamented with architectural elements that imitated, in stucco relief, the fashions that could be seen in the masonry and marble veneers of temples and palaces. This type of décor, established in the homes of Greek nobility throughout the Hellenistic era, is traditionally known as the masonry style or incrustation style.
